| pulmonary oedema | <cardiology> A severe state of increased interstitial fluid within the lung that leads to flooding of the alveoli with fluid. This results in a severe disturbance of gas exchange across the alveolar surface. Often results from the ineffective pump function of the heart (noncardiac causes also exist). (27 Sep 1997) |

| hydraemic oedema | An obsolete term for oedema occurring in states marked by pronounced hydraemia. (05 Mar 2000) |
| solid oedema | Infiltration of the subcutaneous tissues by mucoid material, as in myxoedema. (05 Mar 2000) |
| nephrotic oedema | Oedema resulting from renal dysfunction. (05 Mar 2000) |
| noninflammatory oedema | <clinical sign> Oedema due to mechanical or other causes, not marked by inflammation or congestion. (05 Mar 2000) |
| nonpitting oedema | Swelling of subcutaneous tissues which cannot be indented by compression easily. Usually due to metabolic abnormality, such as increased glycosaminoglycan content, like that which occurs in Graves' disease (pretibial myxoedema) or in early phase of scleroderma. Synonym: brawny oedema. (05 Mar 2000) |
| nutritional oedema | A form of swelling caused by insufficient protein intake resulting in hypoproteinaemia and low plasma oncotic pressure. (05 Mar 2000) |
| dependent oedema | A clinically detectable increase in extracellular fluid volume localised in a dependent area, as of a limb, characterised by swelling or pitting. (05 Mar 2000) |
| Quincke's oedema | A vascular reaction involving the deep dermis or subcutaneous or submucal tissues, representing localised oedema caused by dilatation and increased permeability of the capillaries and characterised by development of giant wheals. (18 Nov 1997) |
| infantile acute haemorrhagic oedema of the skin | A generally benign form of cutaneous vasculitis, characterised by ecchymotic purpura, often in a cockade pattern, and inflammatory oedema in infants. (05 Mar 2000) |
| inflammatory oedema | A swelling due to effusion of fluid in the soft parts surrounding a focus of inflammation. (05 Mar 2000) |
| Yangtze oedema | <dermatology, microbiology> A migrating oedema, or creeping eruption, caused by cutaneous infection by larvae of Gnathostoma spinigerum. Synonym: Yangtze oedema. (05 Mar 2000) |
| laryngeal oedema | Oedema of any region of the larynx from a variety of causes. In the earliest stages it may be difficult to differentiate from infection, although mucosal injection and erythema are found more often in the latter. Allergic oedema may result as a response from provocation induced by foods, inhalants, and drugs. The entire respiratory tract or only an isolated portion of the larynx may be affected. Laryngeal oedema may also be hereditary. Other possible causes of laryngeal oedema include increased capillary pressure due to superior vena cava syndrome, internal jugular vein ligation, lowered plasma osmotic failure induced by renal failure, impaired lymphatic flow, and increased capillary permeability to proteins.

| lymphatic oedema | Oedema due to stasis in the lymph channels. Synonym: leukophlegmasia. (05 Mar 2000) |
